GBJ End Mill Holders 90° Indexable EXN03R C15-16-160

Description

Product Overview

The GBJ End Mill Holders are engineered for high‑performance machining in demanding industrial environments. Featuring a precise 90° indexable geometry, these holders accommodate the EXN03R series of carbide inserts (C15‑16‑160 and C20‑21‑160), delivering consistent cutting angles and superior rigidity. Constructed from premium‑grade steel with a hardened surface treatment, the holders resist wear and maintain dimensional stability even under heavy loads. The anti‑vibration design incorporates optimized mass distribution and damping features that minimize chatter, resulting in smoother surface finishes and longer insert life. Each holder is calibrated to meet ISO standards for tool interchangeability, ensuring seamless integration with a wide range of CNC milling machines and manual setups. The compact form factor allows for easy storage and quick tool changes, reducing machine downtime and increasing overall productivity.

Usage

These holders excel in a variety of machining applications, including slotting, face milling, and shoulder milling on materials ranging from aluminum alloys to hardened steels. Their robust construction makes them suitable for high‑speed machining, where stability and precision are critical. In aerospace component production, the holders provide the accuracy needed for tight tolerances, while in automotive part manufacturing they enable efficient material removal with reduced tool wear. The ergonomic design facilitates easy handling by operators, and the quick‑change indexing system allows for rapid insert replacement, making them ideal for both batch production and custom job shops. Whether used in a fully automated CNC cell or a manual milling station, the GBJ holders deliver consistent performance, helping manufacturers meet stringent quality standards and delivery schedules.

FAQ

What sizes of inserts are compatible with these holders?

The GBJ End Mill Holders are compatible with EXN03R series carbide inserts, specifically the C15‑16‑160 and C20‑21‑160 sizes, which cover a range of cutting widths for versatile machining needs.

Can these holders be used on both CNC and manual milling machines?

Yes, the holders are designed to fit standard spindle interfaces found on most CNC and manual milling equipment, allowing seamless integration across different machine types.

How does the anti‑vibration feature improve machining performance?

The built‑in damping geometry absorbs and dissipates vibration energy generated during cutting, which minimizes tool chatter, enhances surface finish, and extends the life of both the holder and the insert.

What is the recommended maintenance routine for the holders?

Regularly clean the holder to remove chips and coolant residues, inspect the indexing mechanism for wear, and re‑apply a light coating of cutting oil to maintain optimal performance.

Do you offer bulk pricing or custom branding options?

GBJ provides volume discounts for large orders and can accommodate custom branding or packaging requirements to align with your company’s specifications.
